An atom or group of atoms with a negative charge is called an anion. Anions have gained one or more electrons, leading to an overall negative charge.
Ions. Usually negative ions, but not always.
An ion is a particle that carries a charge, either positive or negative, due to losing or gaining electrons. It can be a single atom or a group of atoms that have an overall charge. A molecule is a group of atoms held together by chemical bonds and may or may not carry a charge.
A Polyatomic ion is a covalently bonded group of atoms that has a positive or negative charge and acts as a unit
A polyatomic ion is held together by covalent bonds between atoms. They can be either positive or negative. For example, the ammonium ion, NH4+, has a positive charge, and the sulfate ion, SO42-, has a negative charge.
An atom or group of atoms with a negative charge is called an anion. Anions have gained one or more electrons, leading to an overall negative charge.
A polyatomic ion is a group of atoms with a charge.
An atom or group of atoms having a negative charge is called an anion. Anions are formed when an atom gains one or more electrons, leading to an excess of negative charge. Examples of common anions include chloride (Cl−) and sulfate (SO4 2-).
Ions are formed when atoms have charges. Cations are species with positive charge. Anions are species with negative charge.
a tightly bound group of atoms that behaves as a unit and has a positive or negative charge
It is an ion.
The carboxyl group (-COO-) contributes a negative charge in a molecule due to the presence of the oxygen atoms, which tend to pull electrons toward them, resulting in a partially negative charge on the oxygen atoms.

The atom that attracts electrons more strongly will acquire a partial negative charge in a covalent bond with hydrogen. This can be determined by looking at the electronegativity values of the atoms involved in the bond; the atom with the higher electronegativity will acquire the most negative charge.
polyatomic ions are those ions which carry more than one atom,we can say that a group of atoms having single charge( which may be positive or negative) are polyatomic ions.
